Lightly mark a continuous unit centerline on the
threshold.
Next, mark a continuous unit centerline up each wall,
starting where the threshold centerline meets the wall.
Use a level to ensure the wall centerline is plumb and
straight. The wall centerlines should be a minimum of
the unit height from the threshold.
Note: It is extremely important the unit cen-
terline be continuous and straight to ensure
proper installation.
On the wall selected for installation of the door, check the fit of SC982 Hinge Jamb [2] where
the threshold and wall meet. In many cases the corner will need to be contoured to fit a radius.
Contour the corner as required to ensure proper contact with the wall and threshold.
Proper fit in this area allows the door to be installed on a fiberglass enclosure or walls
with no blocking. Failure to radius the corner for proper fit may cause the door to fall
causing property damage and bodily harm.
Note: It is imperative that SC982 rest on the threshold. Out-of-Level conditions may dictate the
door and SC983 jamb assembly be raised such that SC983 does not contact the threshold. This
installation is permitted, but is to be avoided if possible.
Centerline (CL) is a term used to describe the center or mid-point of the unit. The most common unit
centerline position is the middle of the threshold. CL is marked in when visible in images.
